San Antonio Fire Department calms locals smelling gas-like odor

The unsettling gas-like smell residents reported on Wednesday, June 18, is not dangerous.
San Antonio can breathe a sigh of relief. The unsettling gas-like smell residents reported on Wednesday, June 18, is not dangerous. Officials confirm the odor is mercaptan, a harmless additive used in natural gas.
The San Antonio Fire Department confirmed the odor was harmless in a social media alert. SAFD said it had been besieged with 911 calls from residents worried about a gas leak. According to officials, the chemical release happened on the far South Side.
Boerne residents also experienced the fumes. Confusingly, the Boerne Police Department blamed the odor on a routine line clean-out West Texas Gas was conducting in Leon Valley. The smell was carried by strong winds into the Hill Country town.
Though mercaptan’s distinctive smell may be alarming, its use aids public safety. Natural gas is odorless and would be difficult to detect without the pungent chemical additive. Fire Department officials said the smell should go away soon.
The non-toxic ingredient, however, can cause respiratory irritation, including coughing and shortness of breath. The low concentration of mercaptan in San Antonio’s air is unlikely to cause problems, but those with respiratory sensitivities might hedge their bets by staying inside.
Despite the lack of immediate danger, locals should be advised to play it safe with natural gas. If customers detect the familiar rotten egg aroma indoors, they are advised to immediately leave the premises and call 210-353-4357. Home gas leaks can also be checked with the "soapy water test." When a leak is sprayed with a mixture of dish soap and water, bubbles will form.
